FUTURE FLAPPER

Shake a little leg in Despina Papadopoulos’s flapper-inspired mini-dress, which soaks up the rays during the day so it can set your curves aglow at night. Composed of 448 white circuit-board tiles interspersed with black solar cells, the Day for Night Solar Dress is ready to boogie from sunrise to sunset.

POWER SUIT

Harness the power of the heavens with Zegna Sport’s Ecotech Solar Jacket, which comes equipped with photovoltaic cells to convert sunlight into electricity. Charging the hidden battery pack to full capacity requires four to five hours of direct illumination, but it’s more than enough to juice up an iPod or cellphone.
